Description

Volume seat cover for motors and manufacturing method thereof {Volume seat cover for motors and method of preparing the same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a volume seat cover for a vehicle and a method of manufacturing the same. More particularly, the present invention provides a feeling of volume of a seating surface in a seat cushion and a seat back of an automobile, and prevents a passenger from slipping when seating. At the same time, it provides comfort and has excellent elasticity and elasticity. Therefore, even if it is used for a long time, the leather does not lift up and wrinkles do not occur on the surface of the leather. The manufacturing method is related.

The seat cushion and the seat back are provided with a spring for supporting a load inside the frame which is hinged to each other, and a spring for supporting the load is installed outside the seat cushion And a structure in which the urethane foam pad is surrounded to form a shape, and a cover formed of a fabric or a leather is covered on the outermost side.

In recent years, as the number of automobiles increases and the specifications become more advanced, the seat cover of the vehicle is also preferred to leather, especially natural leather, rather than textile. In addition, a ventilation sheet for cooling the back or hips of a passenger while the occupant's body is in close contact has been developed and widely used not only in high-end vehicles but also in small-sized vehicles.

In the past, the leather seat cover was made by sewing leather on a urethane sponge. However, there was a problem in that the unsealed intermediate portion fell and was pushed and wrinkled due to the load of the occupant. In order to solve this problem, Korean Patent No. 0278555 proposes a method of bonding a leather and a sponge by a method of melting a surface of a sponge using a flame and pressing it in a molten state instead of merely sewing a urethane sponge and a leather Respectively. However, even when the surface of the sponge is melted and joined to the leather, the problem that the leather material is worn out and wrinkled due to the load of the occupant during long-term use is reproduced.

In order to solve this problem, Korean Patent Registration No. 1173225 discloses a technique relating to an anti-skid fabric for an automobile leather seat, which includes a mesh member coated with an adhesive on a three-dimensional spacer fabric and a leather member formed on a fabricated three- And a technique capable of preventing jolting and wrinkling of the bolster portion. Specifically, the technique includes a mesh member formed by coating an adhesive on a portion of a three-dimensional spacer fabric having a three-dimensional structure of a surface layer, an intermediate layer, and a backside layer, and a leather member bonded by the adhesive on the mesh member, And a slab member at a lower portion of the member and a lower member at a lower portion of the slab member. This technology ensures that the elasticity of the leather member is ensured even after the leather member is adhered by coating the adhesive agent in the dot shape and there is no lifting phenomenon even after the elongation and contraction of the leather member and the ventilation function is maintained. It is unnecessary. However, this technique is not easy to produce a three-dimensional spacer having a three-dimensional structure composed of a surface layer, an intermediate layer and a backside layer, and the adhesive is coated in a dot shape.

Korean Utility Model No. 20-2013-0000221 discloses a synthetic resin sheet for a vehicle seat cover comprising a surface layer, a back layer, and an intermediate layer connecting the surface layer and the back layer, wherein the surface layer and the back layer have vent holes The ventilation hole of the surface layer and the ventilation hole of the backside layer are formed at positions corresponding to each other and are formed to have different sizes so that the ventilation is smooth and the leather lifting phenomenon or wrinkle does not occur even for a long period of use Suggestions for non-car seat cover fabrics. However, the mesh net structure used in this technology is not easy to manufacture, and in order to ensure air permeability, vent holes should be formed at corresponding positions of the surface layer, the back layer and the intermediate layer, and it is not easy to have such a structure .

It is characterized by including the intermediate foam 17 for bonding the upper plate and the lower plate by heat bonding of the web film.

In the present invention, the leather 10 may be artificial leather or natural leather, it is preferable that the ventilation hole is formed on the surface.

In addition, a filter foam is attached to the lower part of the leather, the density of which is preferably 60 to 100 ppi (pixels per inch), more preferably 80 to 100 ppi, the thickness of the filter foam 11 is 1.0 to 5.0 mm is preferable, More preferably, it is 1.0-3.0 mm. In the present invention, when the filter foam is larger than the density, the cell size may be too small, and thus the aeration function may be reduced. When the filter foam is smaller than the density range, the adhesive force with the leather may be lowered, so that the lifting may occur when used for a long time. It is preferable to be in a range. In addition, when the thickness of the filter foam 11 is smaller than the range, the seating and comfort of the surface of the seat may be given, and the elasticity and elasticity of restoring the wrinkles of the leather may be insufficient. Since the thickness may be too thick, it is preferable to fall within the above range.

In the present invention, the leather 10 and the filter foam 11 are bonded to form the upper plate 12. The bonding method is a flame lamination or a full bonding or hot melt adhesive, which is attached by hot pressing Melting methods and the like can be used. In this case, as the hot melt adhesive, polyamide, polyurethane, polyethylene terephthalate adhesive may be used, and preferably polyamide thermoplastic resin may be used.

In the present invention, the lower plate 15 is composed of a backing cloth 13 and a foam pad layer provided thereon. The backing cloth is for protecting the lower surface of the volume seat cover to be produced and is composed of a mesh fiber or an olefin film. In this case, the mesh fiber is formed of 10 to 50 denier fibers as a mesh fiber made of synthetic fibers such as polyamide or polyester, and in the case of the olefin film, it is a polyethylene-based flexible synthetic resin material. It is preferable to use what is formed in 5-50 micrometers, and has a density of 0.80-0.95 g / cm <^2> .

The foam pad layer 14 is provided on the backing cloth 13 again. In this case, the foam pad layer 14 is preferably formed of filter foam for the ventilation sheet. It may be configured. The foam pad layer 14 preferably has a thickness in the range of 1.0 to 5.0 mm, more preferably 2.0 to 4.0 mm. When the thickness of the foam pad layer is smaller than the above range, the effect of increasing elasticity and elasticity is not great, and when the foam pad layer is larger than the above range, the entire volume seat cover may be too thick, which is not preferable.

In the present invention, the backing cloth 13 and the foam pad layer 14 may be attached by hot melting and full bonding methods, but it is preferable to use a flame lamination method.

In the present invention, the intermediate foam 17 serves to bond both between the upper plate 12 and the lower plate 15, and is attached in a separated form at regular intervals to give a volume to the sheet. At this time, in order to facilitate the bonding between the upper plate 12 and the lower plate 15, a web film 16 is provided on the upper and lower portions of the intermediate foam 17. The web film is a full bonding or needle. It is attached to the upper and lower portions of the intermediate foam 17 by the method of punching. The web film serves as an adhesive in the bonding process because only the web film is fused without damaging the leather and urethane components in the process of thermocompression bonding the upper plate and the lower plate.

In the present invention, the intermediate foam 17 is preferably formed in a thickness of 8.0 ~ 15.0 mm. When the thickness of the intermediate foam is smaller than the above range, it is difficult to impart volume and comfort. In the present invention, the intermediate foam 17 is preferably composed of a filter foam when producing a ventilation sheet, the density of the filter foam is preferably 20 ~ 70 ppi. If the density of the filter foam is less than the above range, the ventilation function is difficult to smoothly perform. If the density is larger than the above range, the filter foam may be deteriorated. In addition, when manufacturing a non-ventilated sheet, it is not necessary to use a filter foam at this time, it is possible to use a general sponge foam. In the case of the sponge foam, the density thereof is suitably used in the range of 10 to 70 kg / m ³ , but when the density range is smaller than the above range, the recovery force is hardly exerted. Since it is difficult to cycle, it is desirable to keep it in the above range.

Hereinafter, a method of manufacturing a volume seat cover for a vehicle according to the present invention will be described. The volume seat cover for an automobile according to the present invention may be manufactured by a two-step method or a one-step method, which will be described below in part.

First, the two-step method is shown in Figure 4,

A bottom plate 15 having a backing cloth 13 attached to the lowermost layer and a foam pad layer 14 attached to the top of the backing cloth having a thickness of 1.0 to 5.0 mm was prepared and formed thereon. After the intermediate foam 17 having a thickness of 10 and the web film 16 provided on the upper and lower portions is separated and stacked by using the jig 19 for a predetermined interval (a), the upper plate 20 and the lower plate of the heat press The lower plate 15 and the intermediate foam 17 are bonded to each other by being pressed and pressed between the portions 21, and the jig 19 is removed. Then, the upper plate 15 and the intermediate foam 17 are bonded to each other. On the lower part of the leather 10, the upper plate 12 formed by attaching a filter foam 11 of 60 to 100 ppi to a thickness of 1.0 to 5.0 mm is placed (c), and the lower plate is put and pressed into a heat press again. It proceeds in the order (d) which joins the junction of (15) and the intermediate | middle foam 17, and the said upper board 12.

In the production of the volume seat cover by the two-step method, it is necessary to properly adjust the temperature control of the upper plate 20 and the lower plate 21 of the heat press so that the bonding can be secured and a high quality product can be manufactured. In the present invention, the heat press heats the lower plate 21 of the heat press to 100 to 150 ° C. without heating the upper plate 20 in the first step thermal compression bonding the lower plate 15 and the intermediate foam 17. In the two-step thermocompression bonding of the lower plate 15 and the intermediate foam 17 and the upper plate 12 by pressing for 30 to 60 seconds in one state, the upper plate 20 of the hot press is 120 It is preferable to pressurize for 30 to 60 seconds and to join by heating to -140 degreeC, and the lower plate 21 heated to 125-145 degreeC. At this time, in order to protect the surface of the leather in the process of pressing by using a heat press, it is preferable to proceed with thermocompression in the state covered with a leather protective film made of a polyester resin. In addition, the method may further include trimming the outer part after removing the jig 19 to produce a product of a desired shape.

Then, the one-step method is as shown in Figure 5,

It has a thickness of 8.0 to 15.0 mm on the bottom plate 15 having a backing cloth 13 attached to the lowermost layer and a foam pad layer 14 attached to the top of the backing cloth to a thickness of 1.0 to 5.0 mm. The intermediate foam 17 having the web film 16 on the upper and lower portions is separated and stacked at regular intervals using the left and right separating jig 22, and on the stacked intermediate foam 17, under the leather 10. After the upper plate 12 formed by attaching the filter foam 11 having a thickness of 60 to 100 ppi to a thickness of 1.0 to 5.0 mm was deposited (A), the lower plate 15 and the intermediate foam 17 were put into a hot press and pressed. ) And the top plate 12 are joined in one-step (B), and the left and right separation jig is separated in both directions, and the mold is then demolded.

In the production of the volume seat cover by the one-step method as described above, the temperature control of the upper plate 20 and the lower plate 21 of the heat press must be properly adjusted so that the bonding can be secured and a high quality product can be manufactured. In the present invention, since the thermocompression process is performed in one-step, the upper plate 20 and the lower plate 21 of the heat press must be heated at the same time. That is, in the step of thermocompression bonding in one-step, the upper plate 20 of the hot press is heated to 120 to 140 ° C., and the lower plate 21 is pressurized for 30 to 60 seconds while heated to 125 to 145 ° C. It is preferable to join. In addition, it is preferable to perform thermocompression bonding in a state where a leather protective film made of a polyester resin is covered to protect the leather surface in the process of pressing using a heat press. In addition, the method may further include trimming an outer portion after the thermocompression to produce a product of a desired shape.

6 is a plan view and an AA cross-sectional view showing an integrated jig used in a method of manufacturing a volume seat cover for an automobile according to an embodiment of the present invention, and FIG. 7 is a manufacture of a volume seat cover for an automobile according to another embodiment of the present invention. It is a top view and BB sectional drawing which show the left-right detachable jig used for a method.

The integrated jig 19 shown in Fig. 6 is a jig used for manufacturing the volume seat cover by the two-step method, and is formed by forming a foam accommodating portion 19-1 having an appropriate size and number by a wooden work. After the manufacturing process using the first step of the two-step method is used to bond the lower plate and the intermediate foam.

The left and right detachable jig 22 shown in FIG. 7 is a jig used to manufacture the volume seat cover by the one-step method, and forms a foam accommodating portion 22-1 having an appropriate size and number by a wooden work. Manufacture so that the middle part can be separated on both sides. At this time, in order to bond the separated jig may be coupled by a tape or provided with a magnet on the bonding surface to be coupled by a magnetic force. Such a detachable jig can be used in the one-step method to improve the productivity of the volume seat cover by bonding the lower plate, the intermediate foam and the upper plate at once and separating them in both.

In the method of manufacturing a volume seat cover for an automobile according to the present invention, the intermediate foam 17 may vary depending on whether a ventilation sheet is manufactured or a non-ventilated sheet is manufactured. That is, in the present invention, the intermediate foam 17 is preferably composed of a filter foam when manufacturing the ventilation sheet, the density of the filter foam is preferably 20 ~ 70 ppi. In addition, when manufacturing a non-ventilated sheet, it is not necessary to use a filter foam at this time, it is possible to use a general sponge foam. In the case of such sponge foam, it is suitable to use the density in the range of 10-70 kg / m ³ .

In the above description, the lower plate and the intermediate foam (or the lower plate, the intermediate foam and the upper plate) are thermally compressed using the jigs 19 and 22. However, the lower plate 15 using the two-dimensional machining process is not necessary. The intermediate foam 17 and the block may be manufactured to be integrally connected and manufactured by laminating leather thereon. Specifically, by manufacturing a sheet or roll two-dimensionally processed using a filter foam or sponge so that the lower plate and the intermediate foam block are integrally connected, and bonding the leather thereon by a flame lamination, bonding or hot melting method, The lower plate and the intermediate foam block may be integrally formed with the same components. In this way, when the volume seat cover is manufactured, there is no need for jig operation and the productivity can be further improved due to the reduction of the process.

Others that are not described in the method for manufacturing a volume seat cover for a vehicle according to the present invention are the same as those described in the description of the volume sheet cover for a vehicle according to the present invention.

Although it has been described above with reference to the preferred accompanying drawings of the present invention, those skilled in the art can be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below.
